Javier1 · ‎2025-01-17

Ive been trying to use the FDCAN systembootloader from a stm32H757XI, in the past i managed to use the CAN systembootloader from a stm32f405RE succcesfully.

But im getting> nothing , i tried with 125 and 250Kbauds, CAN connceted to PH14 and PH13

Is FDCAN systembootloader compatible with STLINKV3+CubeProgrammer?

Apparently not - see your other thread:

(a limitation of the ST-Link V3 rather than the bootloader itself)

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
